<p>A seal is provided that has a resilient projection extending from an annular sealing member that is arranged to be a snap-fit within an annular recess formed within a bearing. The resilient lip is elastically deformed when inserted into the annular recess and is thus retained therein. The bearing has a retention lip adjacent to the recess against which the resilient lip of the seal abuts when the seal is tried to be removed, thus increasing the force required for removal.</p> |
